The original harmonic oscillator model only regards the cell as a single harmonic oscillator, and a complete understanding of the physical processes involved in harmonic generation experiments in plasmonics is still lacking. In the case in which the plasma structure in a single cell becomes more and more complex, it is not reasonable to regard the entire cell as a single nonlinear oscillator. So expanding the harmonic oscillator model becomes more significant. In this paper, the internal structure of the proposed double U split-ring resonators (DU-SRRs) is regarded as two harmonic oscillators with different resonant frequencies, and the generation process of the enhanced second harmonic is explained by the resonance theorem. The second and third order nonlinear coefficients of the metamaterial are calculated, and the theoretical second harmonic conversion efficiency is obtained by using the second order nonlinear coefficients. Compared with the simulation results of the DU-SRR based on the split-ring resonator, we validate this classical theory as well as the associated numerical algorithm. The ability of the DU-SRR to enhance the second harmonic is proved, and the physical changes inside the cell and the reasons for the enhancement are explained in detail. This method can be used to analyze the nonlinear phenomena in metamaterials with complex cell structures.","PeriodicalId":17280,"journal":{"name":"Journal of The Optical Society of America B-optical Physics","volume":"46 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136254748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By solving a full vectorial polarization-complete evanescent wave equation derived from Maxwell’s equations and all four boundary conditions, we obtain rigorous analytical solutions for the surface states. All analytical dispersion equations and field equations under the three configurations are solved. Simultaneously, the solutions also reveal the intriguing features of surface plasmon polaritons (SPPs) under the gyromagnetic effect. In the polar configuration (where the magnetization is perpendicular to the interface), the gyromagnetic effect uniquely results in candlelight-like field patterns in SPP. In the transversal configuration (where the magnetization is parallel to the interface and perpendicular to propagation), the unidirectional magnetic surface state is found. In the longitudinal configuration (where the magnetization is parallel to propagation), the SPP also exhibits candlelight-like field patterns but manifests a different polarization from the polar configuration. Our results reveal peculiar behaviors of SPPs under the gyromagnetic effect and would deepen the understanding of the magneto-optical effect on interfaces.","PeriodicalId":17280,"journal":{"name":"Journal of The Optical Society of America B-optical Physics","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136254462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The O-band bismuth-doped fiber amplifier (BDFA) has developed rapidly in recent years and has been reported in transmission cases, but its application in clamping is still relatively rare. In past work, we have investigated the clamping effect of a BDFA under a coupler ring cavity under different pumping schemes, while in this work we further improved the structure by replacing the coupler with a circulator to comparatively investigate the limit range of gain stabilization. The experimental results demonstrate that, when the loop loss is 0 dB, the BDFA exhibits nearly identical gain-clamping performance, including flat range and maximum float, with both structures. However, as the loss increases, the circulator structure exhibits a wider gain flatness range than the coupler structure. With pump power of 1 W and VOA loss of 0 dB, the BDFA achieves a maximum gain float of 0.42 dB in the coupler configuration and 0.56 dB in the circulator configuration over an ultra-wide input range of −15dBm to 9 dBm. In addition, the gain flat range under the circulator structure is 3 dB wider than the coupler structure when the VOA loss is 10 dB. Therefore, with the pursuit of a balance between the higher average gain and the widest flat range, it is most advantageous to consider the circulator in the ring cavity. This work gives a valuable reference for the application of the O-band BDFA in gain clamping.","PeriodicalId":17280,"journal":{"name":"Journal of The Optical Society of America B-optical Physics","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135043325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
